本発明はワイヤカツト放電加工装置の線電極材
料として好適な金属材料に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metal material suitable as a wire electrode material for a wire-cut electrical discharge machining device.

一般にワイヤカツト放電加工においては、工作

精度等が指定されると、放電加工時間等は使用す
るワイヤ電極の材質及び線径等によつて左右され
ることになる。 In general, wire cut electric discharge machining is required to have a good surface finish and dimensional accuracy of the workpiece, and to shorten the machining time. It is necessary to improve the machining efficiency due to the electric discharge that occurs between the material and the body. On the other hand, once the power supply type of the electrical discharge machining device, material of the workpiece, surface finish, dimensional accuracy, etc. are specified, the electrical discharge machining time etc. will depend on the material and wire diameter of the wire electrode used. It turns out.

加工時のワイヤ電極のたわみ量（所謂タイコ量
μ）が小さく、親水性がよいこと等々の性質が要
求される。 Therefore, the wire electrode material should be easy to draw, have good conductivity, have a high processing speed when used as an electrode, preferably have a small consumption ratio, and have good heat resistance. Good, especially at high temperatures, without deterioration in tensile strength and difficult to cut during use, difficult to work harden and short circuit, and suitable for two-dimensional processing, three-dimensional processing, and processing at locations where wire electrodes are wound or bent. Further, the wire electrode is required to have properties such as a small amount of deflection (so-called flexure μ) during electrical discharge machining, and good hydrophilicity.
このため、電極材料としては、一般的には純
銅、若しくは黄銅等の銅合金が用いられており、
また、亜酸化銅を添加した銅合金も提案されてい
る。 For this reason, pure copper or copper alloys such as brass are generally used as electrode materials.
Copper alloys to which cuprous oxide is added have also been proposed.
銅電極は導電率の点では良好な値を有するが、
消耗比が60％前後である上、抗張力等の機械的強

ているため、くせが残存しており、ガイド間にお
いて充分大きな張力で張つて移動させるようにし
ないと、充分な直線性が出にくく、加工精度とワ
イヤ断線の問題が相矛盾していた。 Although copper electrodes have good values in terms of conductivity,
The wear ratio is around 60%, and it is also insufficient in terms of mechanical strength such as tensile strength and heat resistance, and brass wire is superior to copper wire in terms of mechanical strength such as tensile strength and processing speed. However, it is somewhat inferior in terms of conductivity and consumption ratio. Brass wire has a tensile strength and hardness that exceeds that of hard copper, that is, it has spring properties, so it has some curls, and unless it is moved with a sufficiently large tension between the guides, it cannot be moved in a sufficient straight line. The problems of machining accuracy and wire breakage were contradictory.
一方、純銅に亜酸化銅Cu2Oを１―５％配合し
た合金線は、導電性が純銅と大差なく、消耗比も
20〜30％前後であり、加工速度も優れているが、
難切断性についてはなお問題がある。 On the other hand, an alloy wire made of pure copper mixed with 1-5% cuprous oxide Cu 2 O has a conductivity that is not much different from that of pure copper and a low wear rate.
The processing speed is around 20-30%, and the processing speed is also excellent.
There is still a problem with difficulty in cutting.

途に使用されていたにすぎなかつた。 On the other hand, there are wire electrodes made of tungsten, molybdenum, or their alloys drawn to a diameter of about 0.1 mm 2 or less, but these were expensive and were only used for special purposes.

分等の輪郭形状の加工が行えないという問題点が
あつた。 In addition, a wire cut electric discharge machining device generally moves a wire electrode from one reel to the other reel, and processes a desired shape by performing electric discharge machining by performing pulse discharge while supplying machining fluid. Therefore, the wire electrode is twisted and bent every time it passes between the brake roller and the pinch roller, between the capstan and the pinch roller, between the guide roller and the guide guide, etc., and as a result, the wire electrode undergoes work hardening. This may result in loss of linearity, or conversely, if processing is attempted at a strongly bent portion of the wire electrode, it may be impossible to obtain a small bending radius, resulting in overhang of the workpiece. For example,
There was a problem in that it was not possible to process the contours of the hollow part of the extrusion die, the cutting edge part of the trim die, etc.

At least one element selected from the group consisting of Zr, Co, Fe and Ti and 0.05 to 1% of rare earth elements;
The remainder is present in the alloy consisting of impurities and Cu.

An alloy for a wire-cut electric discharge machining electrode is described, which contains Zn and one or more of Mn, Mg, and rare earth elements in a total of 0.1 to 3%, with the balance being Cu.

点があつた。 However, the addition of rare earth elements in electrode materials made of Cu-based alloys such as various brass such as Cu and Cu-Zn improves the tensile strength and break resistance, and improves electrical discharge machining performance, especially rare earth elements. Although it is effective in increasing the machining speed, which is thought to be a result of the contribution of elements to the generation of electrical discharge, etc., the amount of deflection of the wire electrode (so-called flexure amount μ) during electrical discharge machining is large;
Moreover, there was a problem that short circuits could not be prevented.
